Due to dwindling capacity for existing aborted fetal cell lines to self-replicate, scientists in China have developed a new aborted fetal cell line, WALVAX 2 that will be used for viral vaccine production. The existing cell lines, MRC-5 and WI-38 are currently used in MMR, Varicella, Hepatitis-A, Shingles, some rabies and some polio vaccines. WALVAX 2 is taken from the lung tissue of a 3 month gestation female who was ultimately selected from among 9 aborted babies. The scientists noted how they followed specific guidelines to mimic WI-38 and MRC-5 in selecting the aborted babies, ranging from 2-4 months gestation. They further noted how they induced labor using a “water bag” abortion to shorten the delivery time and prevent the death of the fetus to ensure live intact organs which were immediately sent to the labs for cell preparation.
